Description
Technical Field
The invention relates to a textile printing and dyeing and functional after-finishing technology, belongs to the field of textile printing and dyeing, and particularly relates to a preparation method of silk with an ultraviolet radiation prevention function.
Background
Silk fabrics are light, thin, soft, high-grade and natural, and are deeply favored by consumers. But the performance of ultraviolet radiation resistance is poor, and when people wear silk products in hot summer, the skin is easily burnt by ultraviolet rays. The ultraviolet ray is a ray with the wavelength of 200-400nm, which is a kind of ray with shorter wavelength and higher energy in the solar ray. In recent years, people gradually recognize that ultraviolet rays directly irradiate the skin, excessive ultraviolet rays cause photochemical reaction, a series of changes of human body functions can be caused, particularly, the damage is caused to the skin, eyes, an immune system and the like of a human body, and a large amount of skin lesions are related to excessive ultraviolet radiation. Therefore, research into uv resistant products has been initiated, and the first developed uv resistant commercial product is uv resistant cosmetics. After 90 s, ultraviolet-resistant fabrics have been rapidly emerging, and among them, the japanese companies are the most prominent, and they have been popular among consumers who successively put out products such as sportswear, shirts, stockings, hats, and sun umbrellas having an ultraviolet radiation-resistant function.
The textile is a surface porous material, can absorb external light, and can reduce the transmittance of light due to diffuse reflection, so that the common textile has certain ultraviolet ray blocking capability. However, in hot seasons, the fabric is light and thin, the ultraviolet ray resistance can not be met only by the ultraviolet ray shielding capability of the conventional fabric, and only by the ultraviolet ray resistance function of the fabric, a protective umbrella can be supported for the skin. In addition, ultraviolet rays also have an adverse effect on the textile itself, which not only discolors the textile, but also causes brittle damage to nylon and cellulose fibers, resulting in a decrease in strength. The ultraviolet protection index (UPF) is an index for measuring the ultraviolet protection performance of the fabric, the UPF represents the shielding capability of the fabric to sunlight, and the larger the value is, the stronger the protection capability is. Generally, the daily fabric UPF is below 5, the fabric does not have ultraviolet radiation protection performance, the UPF is above 30, and the transmittance (T%) is less than 5%, so that the fabric is considered to achieve good protection performance. However, the UPF of more than 30 is only the protection required generally, and the UPF of the product is more than 50 to achieve the protection required more. The development of the product with high protection requirement has important significance for improving the performance of the product and applying the product in special environment, and the development of the functional silk fabric product with the UPF more than 50 has good market prospect.
The preparation and processing principle of ultraviolet resistant textiles is generally to add ultraviolet screening agents to fibers and fabrics, to mix and treat the fibers and fabrics to improve the ultraviolet absorption and reflection capability of the fibers and fabrics. Inorganic ultraviolet screening agents, also known as ultraviolet reflecting agents, achieve the purpose of resisting ultraviolet radiation by mainly reflecting or refracting incident ultraviolet rays. They have no light energy conversion function, and only use the combination of fine powder or superfine powder of ceramics or metal oxide, etc. with fiber or fabric to increase the reflection and scattering effect of fabric surface to ultraviolet ray, so as to prevent the ultraviolet ray from transmitting through the fabric and damaging human skin.
The ultraviolet absorbers are frequently used at home and abroad, but the ultraviolet absorbers have no reactive functional groups, are not easy to fix and are easy to diffuse. And the fabric finished by the non-reactive and small-molecular ultraviolet absorber has poor washability, the ultraviolet-proof effect is difficult to last, and the air permeability, hand feeling and sanitary performance of the fabric are influenced.

As can be seen from the data in Table 2, after 30 times of washing, the UPF value of the real silk fabric is not obviously reduced and is still greater than or close to 50, which shows that the real silk fabric with ultraviolet radiation resistance prepared by the invention has good washing fastness, because the 3,3,4, 4-tetracarboxylic dianhydride benzophenone in the finishing liquid and the real silk fabric are subjected to covalent crosslinking, the finishing liquid has more excellent washing fastness than the traditional coating finishing.
The above embodiments are only for illustrating the invention and are not to be construed as limiting the invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, therefore, all equivalent technical solutions also belong to the scope of the invention, and the scope of the invention is defined by the claims.
